Description
本發明係有關於無線通信系統。特別是,本發明係有關於高速共享控制通道(HS-SCCH)之使用者設備識別碼(UE ID)專用之擾頻序列。The present invention is related to wireless communication systems. In particular, the present invention relates to a scrambling sequence specific to a User Equipment Identity (UE ID) of a High Speed Shared Control Channel (HS-SCCH).
寬頻分碼多重存取(W-CDMA)通信系統係提出一種高速下行封包存取(HSDPA)方法。這種高速下行封包存取(HSDPA)方法係提供高下行資料速率,藉以支援多媒體服務。The Wideband Code Division Multiple Access (W-CDMA) communication system proposes a High Speed Downlink Packet Access (HSDPA) method. This High Speed Downlink Packet Access (HSDPA) method provides high downlink data rates to support multimedia services.
為支援這種高速下行封包存取(HSDPA)方法,高速共享控制通道(HS-SCCH)係加以使用。這些高速共享控制通道(HS-SCCH)係用以發送必要控制資訊至使用者設備(UE)。各個高速共享控制通道(HS-SCCH)係具有兩個部分,其分別稱為第一部分(PART I)及第二部分(PART II)。第一部分(PART I)係承載使用者設備(UE)需要之時間關鍵資訊。該資訊係包括高速實體下行共享控制通道(HS-PDSCH)使用之通道訊息碼設定及調變類型,其係承載高速下行封包存取(HSDPA)負擔。該資訊係支援高速下行封包存取(HSDPA)所必要,因為高速下行封包存取(HSDPA)係使用適應性調變及編碼(AMC)方法。To support this high speed downlink packet access (HSDPA) method, the High Speed Shared Control Channel (HS-SCCH) is used. These High Speed Shared Control Channels (HS-SCCH) are used to transmit the necessary control information to the User Equipment (UE). Each High Speed Shared Control Channel (HS-SCCH) has two parts, called the first part (PART I) and the second part (PART II). The first part (PART I) is the time critical information needed to carry the User Equipment (UE). The information includes the channel message code setting and modulation type used by the high-speed entity downlink shared control channel (HS-PDSCH), which carries the high-speed downlink packet access (HSDPA) burden. This information is necessary to support High Speed Downlink Packet Access (HSDPA) because High Speed Downlink Packet Access (HSDPA) uses the Adaptive Modulation and Coding (AMC) method.
為取得第一部分(PART I)資訊,各個高速下行封包存取(HSDPA)使用者設備(UE)係監控至多四個高速共享控制通道(HS-SCCH)以取得其資訊。一特定使用者設備(UE)之資訊係利用其使用者設備識別碼(UE ID)專有之擾頻序列,與 其他使用者設備(UE)進行區別。該使用者設備(UE)係利用其使用者設備識別碼(UE ID)專有之擾頻序列,處理各個監控之高速共享控制通道(HS-SCCH),藉以偵測該使用者設備(UE)預期之高速共享控制通道(HS-SCCH)。處理後,該使用者設備(UE)係決定:在那一個高速共享控制通道(HS-SCCH)上,資訊係利用其擾頻序列承載。To obtain the first part (PART I) information, each High Speed Downlink Packet Access (HSDPA) User Equipment (UE) monitors up to four High Speed Shared Control Channels (HS-SCCH) to obtain its information. The information of a particular user equipment (UE) utilizes its user equipment identifier (UE ID) proprietary scrambling sequence, and Other user equipment (UE) makes a distinction. The user equipment (UE) processes each monitored high-speed shared control channel (HS-SCCH) by using its user equipment identification code (UE ID)-specific scrambling sequence to detect the user equipment (UE). Expected High Speed Shared Control Channel (HS-SCCH). After processing, the user equipment (UE) determines that on that high speed shared control channel (HS-SCCH), the information is carried by its scrambling sequence.
直至最近,一10位元之使用者設備識別碼(UE ID)係用以做為該使用者設備(UE ID)專有擾頻序列之基礎。在這個例子中,該使用者設備識別碼(UE ID)係轉換為一40位元擾頻序列。為了將該10位元使用者設備識別碼(UE ID)轉換為該40位元使用者設備識別碼(UE ID)專有之擾頻序列,該10位元使用者設備識別碼(UE ID)係利用一Reed-Muller方塊處理,用以產生一32位元訊息碼。該產生訊息碼之前8個位元係重覆附加至該32位元訊息碼之後面,藉以產生一40位元訊息碼。Until recently, a 10-bit User Equipment Identifier (UE ID) was used as the basis for the User Equipment (UE ID) proprietary scrambling sequence. In this example, the User Equipment Identity (UE ID) is converted to a 40-bit scrambling sequence. In order to convert the 10-bit user equipment identifier (UE ID) into the 40-bit user equipment identifier (UE ID)-specific scrambling sequence, the 10-bit user equipment identifier (UE ID) It is processed by a Reed-Muller block to generate a 32-bit message code. The first 8 bits of the generated message code are repeatedly appended to the back of the 32-bit message code to generate a 40-bit message code.
雖然該使用者設備識別碼(UE ID)長度最好能夠延伸至16個晶片,然而,高速共享控制通道(HS-SCCH)依目前方法係使用一10位元使用者設備識別碼(UE ID)。該使用者設備識別碼(UE ID)係轉換為一40位元擾頻序列。為了將該10位元使用者設備識別碼(UE ID)轉換為該40位元擾頻序列,該10位元使用者設備識別碼(UE ID)係利用一Reed-Muller方塊處理以產生一32位元訊息碼。另外,該產生訊息碼之前8個位元係重覆附加於該32位元訊息碼之後面以產生一40位元訊息碼。Although the user equipment identification code (UE ID) length is preferably extended to 16 chips, the High Speed Shared Control Channel (HS-SCCH) uses a 10-bit User Equipment Identity (UE ID) according to the current method. . The user equipment identification code (UE ID) is converted into a 40-bit scrambling sequence. In order to convert the 10-bit user equipment identifier (UE ID) into the 40-bit scrambling sequence, the 10-bit user equipment identifier (UE ID) is processed using a Reed-Muller block to generate a 32. Bit message code. In addition, the first 8 bits of the generated message code are repeatedly appended to the 32-bit message code to generate a 40-bit message code.
為降低錯誤偵測之發生,各個使用者設備(UE ID)之產生擾頻訊息碼間最好能夠具有完善之區分。因此,擾頻訊息碼最好能夠利用交替方式產生。In order to reduce the occurrence of error detection, it is better to have a perfect distinction between the scrambling message codes generated by each user equipment (UE ID). Therefore, the scrambled message code can preferably be generated in an alternating manner.
一種訊息碼,其產生以擾頻或解擾頻關連於一特定使用者之一高速共享控制通道(HS-SCCH)之資料。該特定使用者設備之一使用者識別碼係具有L位元。一1/2速率迴旋編碼器係利用一1/2速率迴旋訊息碼,處理該使用者識別碼之至少該等位元,用以產生擾頻一高速共享控制通道(HS-SCCH)之一訊息碼。A message code that generates data that is scrambled or descrambled and associated with a High Speed Shared Control Channel (HS-SCCH) of a particular user. One of the user devices of the particular user device has an L bit. A 1/2 rate cyclotron encoder processes at least the bits of the user identification code using a 1/2 rate convolutional message code to generate a message of a scrambled high speed shared control channel (HS-SCCH) code.
雖然該等較佳實施例係配合本發明之較佳應用詳細說明,藉以用於第三代合作計畫(3GPP)寬頻分碼多重存取(W-CDMA)通信系統之高速下行封包存取(HSDPA)方法,本發明亦可以應用於其他類型之分碼多重存取(CDMA)通信系統。第1A及1B圖係表示使用者設備識別碼(UE ID)專有之擾頻序列電路。長度L之使用者設備識別碼(UE ID)XUE係輸入至該電路。長度L可以是任何長度,諸如:8位元、10位元、16位元等等。該使用者設備識別碼(UE ID)XUE ={XUE1 、...、XUEL }係輸入至一1/2速率迴旋編碼器10,如第1A圖所示。隨著該使用者設備識別碼(UE ID),額外位元(諸如:"0")亦可以附加至該輸入字串之末端,用以延伸該輸入字串之長度、或該輸出字串之長度。使用一1/2速率迴旋編碼器10可以在不同使用者設備識別碼(UE ID)產生之輸出字串間,提供 一高標準之訊息碼區分。另外,目前之第三代合作計畫(3GPP)寬頻分碼多重存取(W-CDMA)通信系統係利用一1/2速率迴旋編碼器10以完成一前向誤差校正(FEC)技術。因此,該迴旋編碼使用者設備識別碼(UE ID)專有之擾頻序列並不需要利用額外硬體產生。編碼後,基於該輸出字串之長度,一速率匹配階段12便可以加入刺穿位元,用以取得一想要之字串長度。Although these preferred embodiments are described in detail in conjunction with the preferred application of the present invention, the high speed downlink packet access for the 3rd Generation Partnership Project (3GPP) Wideband Code Division Multiple Access (W-CDMA) communication system is utilized ( The HSDPA) method, the present invention is also applicable to other types of code division multiple access (CDMA) communication systems. Figures 1A and 1B show a scrambling sequence circuit that is unique to the User Equipment Identification Number (UE ID). The user equipment identifier (UE ID) XUE of length L is input to the circuit. The length L can be any length, such as: 8-bit, 10-bit, 16-bit, and the like. The User Equipment Identity (UE ID) X UE = {X UE1 , ..., X UEL } is input to a 1/2 rate cyclotron encoder 10 as shown in FIG. 1A. With the user equipment identification code (UE ID), an extra bit (such as "0") may also be appended to the end of the input string to extend the length of the input string or the output string. length. Using a 1/2 rate cyclotron encoder 10, a high standard of message code discrimination can be provided between output strings generated by different user equipment identification codes (UE IDs). In addition, the current 3rd Generation Partnership Project (3GPP) Wideband Code Division Multiple Access (W-CDMA) communication system utilizes a 1/2 rate cyclotron encoder 10 to perform a forward error correction (FEC) technique. Therefore, the scrambled user equipment identification code (UE ID)-specific scrambling sequence does not need to be generated with additional hardware. After encoding, based on the length of the output string, a rate matching stage 12 can add a puncture bit to obtain a desired string length.

The 16-bit user equipment identifier (UE ID), X UE = {X UE1 , ..., X UE16 }, is input to a 1/2 rate cyclotron encoder 14 and 8 bits "0""Append to the end of the input string. Therefore, the input string is X UE1 , . . . , X UE16 , 0, 0, 0 , 0, 0 , 0, 0 , 0. After processing by the 1/2 rate whirling encoder 14, the output message code has a length of 48 bits, that is, C UE = {C UE1 , ..., C UE48 }.
為了將該訊息碼之長度降低至40位元之較佳長度,8個位元最好能夠刺穿。第2B圖係表示執行刺穿之速率匹配階段16。速率匹配階段16後,該擾頻訊息碼之有效長度係40位元。In order to reduce the length of the message code to a preferred length of 40 bits, 8 bits are preferably pierceable. Figure 2B shows the rate matching phase 16 of performing the puncture. After the rate matching phase 16, the effective length of the scrambled message code is 40 bits.
第4圖係表示一簡化使用者設備,其係利用使用者設備識別碼(UE ID)專有之擾頻訊息碼,對一高速共享控制通道(HS-SCCH)進行解擾頻動作。該使用者設備識別碼(UE ID)擾頻訊息碼係利用一互斥或(XOR)閘20,舉例來說,與該接收高速共享控制通道(HS-SCCH)混合,用以回復該編碼高速共享控制通道(HS-SCCH)資料。Figure 4 shows a simplified user equipment that descrambles a high speed shared control channel (HS-SCCH) using the user equipment identification code (UE ID) proprietary scrambling message code.
